This invention relates to heating devices ent material;preferably it is made of copfor buildings in Which there is employed a per or some other non-corrosive metal.

It is the fully with reference to the accompanying chief object of the present invention to drawlngs in which:

The heut-radlatlng sectional plate with the pipe inner pipe or tube may extend through only or tube forthe hot gaseous products of sinuone of the conduits or passages in which case ous formation and extending through all .of it may be of straight formation or it may the passages or conduits shown. extend through a number of the conduits or F lgures 5 and 6 are vertical sections taken passages in succession in which case it may approximately on the lines 55 and 66 of be of sinuous formation. The inner pipe or F; ure hand tube may be made of the same material as v igure ;7 is a-horlzontal section taken apthe outer conduits or passages or of a diflerproximately 11 the line 77 of Figure 4. 1-00 burner from which the hot gaseous products are derived and which is directed into the in let end of the pipe or tube B through an enlargement or hood B H is the suction fan connected to the outlet end of the pipe or tube B and operating to draw the hot products of combustion from the burner F through the pipe or tube, and, after having communicated their heat to the Water or other heating me dium which surrounds the said pipe or tube and circulates in the inter-communicating system of conduits or passages, to discharge them in a cool condition through an exhaust pipe 9 leading to the exterior of the room.

In Figure l the pipe or tube B for the hot gaseous products is of straight formation and extends through only the lowermost horizontal conduit or passage a which isprovided with fluid-tight glands a at the ends where the pipe or tube enters and leaves the conduit or passage, said glands serving also to support the pipe with a space C around it for the water or other heating medium, said space communicating directly with the water or other heating medium in the other conduits or passages, so that it can circulate freely through the entire inter-communicating system.

In Figures 2 and 3 the pipe or tube B for the hot gaseous products is of serpentine form housed within the chamber or casing K, and having its inlet and outlet ends enterin and leaving the same through fluid-tight g ands at (1 This chamber or casing is filled with the water or other heating medium employed which communicates directly with the water or other heating medium contained in the conduits or passages radiating sectional plate A, so that free circulation of the water um can take place throughout the whole intier-communicating system as in the last pre- :the room as before.

ceding arrangements. The gas burner F is situated withina space or compartment Z0 in the said chamber or casing K and immediately below the inlet end'of the serpentine pipe or tube B,

In Figures 4 .to 7 the pipe or tube B for the hot gaseous products passes in succession through several of the horizontal conduits or passages'a, the ends of the portions of the said pipe that extend through the glands b, b being alternately connected together by bent or angle tubes 12 b so as to constitute a continuous sinuous pipe or tube. The inlet end of the uppermost portion of the pipe or tube has an enlarged portion or hood ]3 through which the hot gaseous products from the gas burner F are drawn by the suction fan II and discharged in a cool condition through an exhaust pipe as in the other examples already described. The opposite ends of the provided With panels J, J having hinges y, connecting them to the body portion of the plate, one of the panels carrying the gas burner F. By thus hinging the panels to the heat-radiating plate, provision is made for enabling the connections of the bent or angle tubes 6 with the pipe or tube B to be inspected or repaired and also for enabling the gas burner to be ignited. The spaces G surrounding the pipe or tube B are filled with the Water or other heating medium employed which is in free communication with that contained in the other portions of the conduits or passages constituting the inter-communicating system.

Instead of the hot gaseous products being derived from a gas flame as shown in the case a bi-metallic or other suitable form of thermostatic device may be used in association with the pilot light for causing the supplyof gas to the burner to be cut off in the event 'of the pilot light becoming unintentionally extinguished.

' A thermostatic device may be provided in the room where the heating device is situated for controlling the amount of gas supplied to the burner in accordance with the temperature of the room. 7 r In the ensuing claiming clauses when I refer to a heat-radiating plate I intend to include a plurality of plates and when I refer to the wall of the room I intend to include the'ceiling. i 7

What I claim and desire to secure by Letters Patent of the United States is 1. A heating device for buildings, comprising in the combination of a substantially fiat and extensive metal heat-radiating plate adapted to be aifixed to the wall of a room to be heated having conduits formed thereon to constitute an intercommunicating system through Which a heating fluid circulates, a pipe passing through a portion of said fluid and forming a passage for hot gaseous products of combustion derived from a burner, means for causing said hot gaseous products to pass through said pipe and eventually to escape into the open air after parting with their heat to the fluid and means for enabling said burner and the pipe to be readily reached.

2. A heating device for buildings, comprising the combination of a substantially flat and extensive heat-radiating plate adapted to be aflixed to the Wall of a room to be heated having conduits formed thereon to constitute an inter-communicating system through which a heating fluid circulates, a pipe of sinuous formation passing through a plurality of said conduits and forming a passage for hot gaseous products of combustion derived from a burner, means for causing said hot gaseous products to pass through said pipe and eventually escape into the open air and displaceable panels for enabling said burner and the pipe to be readily reached.
